Patented Oct. 20, 1931 1 UNITEDSTAQ'FTES WI LIAM 1v. CROPPER, or'mixme'ron, KENTUCKY wmnow sAsn AsTEn R My invention relates to "improvements in window sash fasteners and moreparticularly to a device for locking the sashes of a window in open or ventilating position.

5 An important object of my invention is the provision of a, device of this character which will lock the sashes of a window 1n vent1lating position and which cannot be manipulated fromt-he exterior of the window. 10 2 Another object of my invention is to provide a device of the above mentioned character which is simple of construction and operation, inexpensive to manufacture and install,

and strong and durable in use.

i5 Other objects and advantages of my invention will be "apparent during the course of the following description. f

In the accompanying drawings, which form apart of this specification and'wherein "20 like charactersof reference den corresponding parts throughout the same, l

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the'numeral 10 desig- 40 nates the frame of a window having an upper isash 11 and a lower sash 12.

vided with an opening 13 spaced a substantial distance-from thetop of'the sash and extending completely through the s ash. A bolt 14 having an enlarged head is arranged in the opening13 and when the head of the-bolt abutsagainst theinner face of the sash rail, its endprojects'a substantial distance beyond When-the 15 is pivoted about the screw 17 into its lowermost position, the locking bolt is insertl f I Application and June 9, 1930, 'seiiaino. 466,027.

upper sash '11' is lowered it will rest upon the projecting outer end of the b0lt14, as shown in Figures 4 and 5, the bolt acting as guard plate .15 and through the collar 16- into the sashrail at a point above the opening 3 1 13, and is firmly secured to the sash rail by means of'suitable screw-threads or the like.

The lower end of the guard plate 15 is pro vided with an opening l8 having a keyway or notch on its upper side, the' opening 18- being adapted tocorrespond, whenthe plate 0 is in its lower position, with an opening or bore 19 in the sash rail, which does not extend entirely through the sash rail. A look bolt '20 is adapted to extend through the opening 18 and into'theope'riingit). The bolt 20 is provided with an enlarged flattened head 21 and a peg or key 22 spaced from the head and extending radially from the bolt.

* 1VVhen the bolt 14 is in place and the plate i ed in the openings 18 and 19 and the key 22 passes through the keyway in the plate. The

locking bolt 20 is then rotated to move the key away from the keyway andthe bolt 14 is locked in position against removal, by the guard plate. The bolt l4 cannot be pushed through the opening 13. to'allow the upper sash to pass until the locking bolt 20 is rotated and withdrawn, and the guard plate I pivoted into the positionsho'wn' in Figure 3.

The side rail of the lower sash 12 is pro- In order to'lock the lower sashin apar- V tially raised position, I provide the edge of the guard plate! nearest the window frame with a lateral extension 23 having a rounded lower, end. a A keeper 24 is formed with an open side, the other side of the keeper being .operative j position,

groove which receives the lower sash. When the guard plate 15 is swung into its lower position the lateral extension 23 enters the keeper 24 and prevents movement of the lower sash in either direction.

The keeper 24 is so arranged that when the plate 15 engages the keeper, the lower window sash will be raised sufficiently to allow ventilation. The upper sash may then be lowered to rest upon the bolt 14 and the win dow will then ventilate above and. below the sashes. While either sash may be opened, and the other remain closed, it is preferred to lock both sashes in partially open position.

It will be seen that the guard plate 15 acts to prevent removal of the bolt 14; as well as engaging the keeper 24 to lock the lower sash.

While I have shown and described the preferred embodiment of my invention it is to be understood that various changes in the size, shape, and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, what I claim and desire to protect by Letters Patent is 1. In a ventilating device for a window having upper-and lower sliding sashes, the lower sash having an opening extending therethrough at a point spaced from its up per end, a bolt arranged in said opening and extending beyondthe outer face of the sash for a substantial distance, a guard plate pivoted to the inner face of the lower sash adjacent the bolt and adapted to be swung over the inner end of the bolt to prevent its removal, and means to secure the pivoted guard plate in its operative position.

2. In a ventilating, device for a window having a frame and upper and lower sliding sashes, a stop member extending through the lower sash at a pointspaced from the upper end thereof and projecting outwardly beyond the sash for a substantial distance, a guard plate secured to the lower sash adjacent the stop member and adapted to be moved to cover the inner-end of the stop member, a keeper on the window frame and a lateral extension 011 the guard plate adapted to enter said keeper.

3. In a ventilating device for a window having aframe and upper and lower sliding sashes, the. lower sash having an opening therethrough spaced from the upper end thereof, a bolt arranged in said opening and projecting beyond the sash. for a substantial distance, a guard plate pivoted to the lower sash adjacent the opening therein and adapted to cover the 1nner end of the bolt, a keeper secured to the window frame, a member on the guard plate adapted. to engage said keeper, andvmeans to secure said. guard plate in 4:. In a ventilating device for a window having a frame and upper and lower sliding sashes, the lower sash having an opening therethrough spaced from the upper end thereof, a bolt having an enlarged head, said bolt being arranged in said opening and projecting outwardly beyond the sash for a substantial distance, a guard plate spaced from said sash and pivoted thereto at a point adjacent the opening therein, said plate being adapted to cover the head of the bolt when in its operative position, a keeper secured to the window frame, and a lateral extension on the guard plate adapted to engage said keeper when the plate is in its operative position.

5. In a ventilating device for a window having upper and lower sashes, the lower sash having an opening therethrough, a bolt having a head at one end, said bolt being relnovably arranged in said opening in the sash and projecting a substantial distance there.- beyond, a guard plate pivoted to said lower sash adjacent the opening therein and adapted'to cover the head of the bolt when arranged in its operative position,-said plate having an opening therein provided with a notch, said opening in the plate registering with an opening in the sash in the operative position of the plate, and. a locking bolt adapted to be received in the registering openings in the plate and sash. and having a key adapted to fit into the notch in the plate opening.

6. In a ventilating device for a window having, a frame and upper and lower sashes, the lower sash having an opening therethrough, a bolt having a head at one end, said bolt being'removably arranged in said opening in the sash and projecting a substantial distance therebeyond, aguard plate pivoted to said lower sash adjacent the opening therein and adapted to cover the head of the bolt when arranged in its operative position, said plate having an opening therein provided with a notch, said opening in the plate registering with an opening in the sash in the operative position of the plate, a locking'bolt adapted to be received in. the registering openings in the plate and sash and having a key adapted to fit into the notch in the plate opening, a keeper secured to the window frame, and a lateral extension on said guard plate adapted to engage said keeper in the operative position of the guard plate.

7. In a ventilating device for the sashes of a window, a removable stop member extending through one of the sashes and projecting therebeyond to provide a stop for the other sash, a movable guard plate-adapted to be and projecting. therebeyondtorprovide a stop 1:30

for the other sash, a movable guard plate adapted to be moved over a portion of the stop member to prevent/its removal, and means on said guard member to engage the window frame.

In testimony whereof I afl'lx my signature.
